Li-ion Battery Cathode Optimization

The development of Li-ion batteries with high energy density and discharge/recharge rates is essential to their utilization in transportation, energy storage, and portable electronics. In addition, the development of Li-ion batteries with dense, 3D architectures could enable micropowered microelectromechanical systems (MEMS) and independently powered 'smart dust' particles for highly distributed computing.

Researchers at Purdue University have developed a low-cost, environmentally inert, Li-ion battery. This battery, based on lithium iron phosphate, has been fabricated with improved discharge/recharge rates compared to previous Li-ion battery cathodes. The battery also offers a high-density microstructure for improved performance and maximized ion diffusivity and electronic conductivity.
